Selective catalytic reduction (SCR)

Selective catalytic reduction (SCR)

 SCR denitration technology refers to the effect of medium temperature catalyst (mainly used in power plant boilers) or low temperature catalyst (mainly used in coke ovens and industrial kilns) in a suitable temperature range (low temperature: 160 ~ 320 ℃, medium temperature 320 ~ 420) ℃), the reducing agent selectively reduces NOx in the flue gas to N2 and H2O to reduce NOx emissions. .

Features

    • The denitration efficiency is high, generally above 90%;
    • technology is mature and widely used;
    • ammonia has a low escape rate and less pollution to the air preheater.
